Question

Formation of a solution from two components can be considered as:
(i) Pure solvent $\to$ separated solvent molecules, $Δ H_{1}$
(ii) Pure solvent $\to$ separated solute molecules, $Δ H_{2}$
(ii) Separated solvent and solute molecules $\to$ solution, $Δ H_{3}$
Solution so formed will be ideal if

Δ H_{s o l n .} = Δ H_{1} + Δ H_{2} + Δ H_{3}

Solution

The correct option is A $Δ H_{s o l n .} = Δ H_{1} + Δ H_{2} + Δ H_{3}$
Solution so formed will be ideal if $Δ H_{s o l n .} = Δ H_{1} + Δ H_{2} + Δ H_{3}$
Adding (i) to (iii)
pure solute + pure solvent $\to$ solution;
$Δ H = Δ H_{1} + Δ H_{2} + Δ H_{3}$
